They already "have to" produce the best watch possible
It is already the politic of the Brand.
So why?
I agree with some points above. How can you call that a seal? A seal means independant and for everyone who one to get to a standard.
Parmigiani Fleurier created an interesting seal for the same reasons as Patek, not happy enough with the Geneva seal. Chopard LUC and Bovet (I think) followed it. If they were unhappy why did they follow it?
Putting on a decoration the requirement to make a Patek Philippe? That is what it is.
This is completely meaningless and calling it a seal imho doesn't respect the customer and "amateurs" of the brand, it is thinking of them as dummies.
I loved what I read of Thierry Stern interview. I love Patek products, the 5970p or the 5131j are just marvels that no other brand can compete with.
But this seal is a complete joke, and one of very bad taste.
Best regards
François
